Renewed December 17, 1929.

This invention relates to a stirring and mixing device which isparticularly designed as a means adapted to be attached to a paint canor container for stirring the same to mix the solid or heavieringredients with the liquid or lighter ingredients.

Practically all varieties of paints, lacquers or other similar coatingsubstances contain a heavy or solid ingredient which is suspended in theliquid or lighter ingredient when they are properly mixed together foruse. Invariably the heavier or solid ingredient settles in the bottom ofthe container and forms a viscous mass if permitted to stand for anyappreciable length of time, which sediment or mass is difiicult to stirfor remixing with the liquid ingredient. The usual practice is to employa stick or other similar makeshift stirring implement of this nature,which in addition to being tiresome and difficult consumes considerabletime and entails untold labor.

The present invention comprehends an im proved means designed as anattachment for a paint container which greatly facilitates and expeditesthe stirring and remixing of the liquid and solid ingredients, inaddition to functioning as a means for thoroughly mixing various colorpigments.

The invention more specifically comprehends a stirring and mixing deviceincluding a rotary blade and manipulating crank and means for supportingand mounting the same on a container whereby the blade is permittedaxial downward movement from an initial position resting on the uppersurface of the solid mass to a final position in contact with the bottomof the container, said blade gradually moving down on the upper level ofthe mass as the same is dissolved and suspended in the liquidingredient.

Other objects reside in the simplicity of construction and mode of useof the device, the facility with which it may be attached to the paintreceptacle or removed therefrom, the economy with which it may beproduced and the general efficiency derived therefrom.

With the above recited and other objects in view, reference is had tothe following description and accompanying drawings, in

which there is exhibited one example or embodiment'of the invention,while the claim defines theactual scope of the same.

1 In the drawings:

Figure 1 is a vertical sectional view through a paint containerillustrating the stirring device associated therewith, parts of thedevice being shown in section to disclose the underlying structure. 1

Figure 2 is a horizontal sectional view taken approximately on the lineindicated at 2-2 in Figure 1.

Figure 3 is a fragmentary sectional view illustrating the devicesupported on a different type of container.

Referring to the drawings by characters of reference, 10 designates ashaft which is provided with a plurality of radially disposed blades 11,preferably constructed from lengths of heavy wire or rods bent uponthemselves to form superposed arms 12 extending through the shaft 10 andconnected by a bight 13. In practice, the bight portions 13 of theseveral blades will be spaced at different relative distances from theshaft 10 so that they will move in different paths and contact withdifferent portions of the contents. The bight portion which is spacedfarthest away from the shaft has an outwardly offset portion 14: whichwill engage with the inner wall of the container and effect thedislodgment of the ingredients therefrom. r

The means for attaching and supporting the shaft, and blades forrotation within the container, consists of a pair of invertedsubstantially U-shaped frame elements 15 including a bight portion 16and a pair of depending arms 17 the bight portion 16 being arranged incrossed relation and having aligned central apertures 18 serving as abearing within which the shaft is loosely journaled for axial movement.The lower ends of the arms 17 are attached to an annulus or ring 19which is of such a diameter as to closely fit within the upper open endof a receptacle A. From their points of connection with the annulus,thearms 17 are offset outwardly to provide terminals 20 spaced from theouter periphery of the annulus and engaging over the outer side of theupper end of the container A. A crank arm 21 having a handle 22 isconnected with the upper end of the shaft and constitutes means formanipulating the device.

In use and operation, after the supporting frame is fitted to the upperend of the container, the blades 11 will sinkinto the liquid contents Buntil they contact with the solid 10 or heavier ingredients C at thebottom of the receptacle. By turning the crank hane dle 22 and exertinga slight downward pressure thereon, the blades will gradually erode thesolid or heavier ingredients and mix and 15 suspend the same in theliquid or lighter ingredients B, the blades and shaft gradually movingdownwardly astlie level of the solid ingredients recedes. In view of thefact that some containers are provided with an inwardly projectingflange D having an annular groove or depression E, the terminals 20 ofthe arms 17 are extended below the lower end of the annulus or ring 19whereby the deviceimay be supported on this form of container, asillustrated in Figure 3 of the drawings.

From the foregoing, it will thus be seen that a simple, effective andhighly efficient stirring and mixing apparatus has been devised byvirtue of which coating materials such as paints or lacquers may bereadily stirred and mixed for use.

hat is claimed is:

A paint stirring and mixing attachment for paint receptacles, includinga shaft having a crank handle for manipulating the same, radiallydisposed blades carried by the shaft and a frame for attachment to thereceptacle, said frame including a pair of crossed substantiallyinverted U-shaped members, the intersecting bight' portions of which areprovided with aligned openings constituting a bearing for the, shaft,and an annulus connecting the lower ends of the depending legs of themembers, the free terminals of the legs being outwardly offset topresent inconjunction with the annulus embracing means for the upperedge of the receptacle.
